GCL Series Robotic Cycloidal Gearboxes

GAM Enterprises, Inc.

GAM’s GCL Series Robotic Cycloidal Gearboxes provide low backlash and high rigidity for horizontal and vertical robotic and motion control applications.


  • Backlash of ≤1 arcmin with lost motion of ≤1 arcmin
  • Withstands the frequent start-stop impact loads of industrial robots with impact resistance 5x nominal torque
  • Multi-tooth meshing for torsional rigidity
  • Flange output in 7 sizes with nominal output torque of 167 to 4410 Nm and ratios of 57:1 to 192.4:1
  • Flanged hollow output in 6 sizes (up to 138 mm through hole) with nominal output torque of 490 to 4900 Nm
  • Available as
    • Component with loose input shaft/pinion (GCLC-F, GCLC-H)
    • Gearbox with cover, integrated input, and motor mounting plate (GCL-F)
  • Drops in for many competitors’ products
  • Integrated motor adapter plate ready to mount your motor


The GCL is well suited to high-end industrial robotics and motion control applications with its ability to withstand start-stop impact loads five times nominal torque.
